[−][src]Struct ndarray_npy::NpzReader
Reader for .npz
files.
Example
#[macro_use] extern crate ndarray; extern crate ndarray_npy; use ndarray::prelude::*; use ndarray_npy::NpzReader; use std::fs::File; let mut npz = NpzReader::new(File::open("arrays.npz")?)?; let a: Array2<i32> = npz.by_name("a")?; let b: Array1<i32> = npz.by_name("b")?;
Methods
impl<R: Read + Seek> NpzReader<R>
[src]
pub fn new(reader: R) -> Result<NpzReader<R>, ReadNpzError>
[src]
Creates a new .npz
file reader.
pub fn len(&self) -> usize
[src]
Returns the number of arrays in the .npz
file.
pub fn names(&mut self) -> Result<Vec<String>, ReadNpzError>
[src]
Returns the names of all of the arrays in the file.

&mut self,
name: &str
) -> Result<ArrayBase<S, D>, ReadNpzError> where
S::Elem: ReadableElement,
S: DataOwned,
